Detailed numerical solutions for obliquely propagating electromagnetic waves near the second harmonic electron cyclotron frequency have been obtained for a plasma of density around the cutoff density of the ordinary mode (O-mode). In a tokamak plasma satisfying a relatively loose condition, a launched O-mode of moderate n/sub parallel/ pass through locations where several branches of electromagnetic hot plasma modes with large right hand components may exist; one of them is the branch of the extraordinary mode (X-mode) and others are new modes. Possibilities of electron heating through mode conversions to those modes are discussed.
